Lets See Your Favorite Cambrian Fossil


PRK

Recommended Posts

just the standard wheeler trilos for me, found years ago with forum member ebrocklds, well before the advent of this fine forum. he's a utah local but hasnt posted in a while; try flushing him out in the open for some pics of his personal collection.

Since size always matters the choice for me is this behemoth trilobite part and counterpart from the middle Cambrian of Morocco. This trilobite is not only remarkable for its large size but also because it is a 99% unrestored and authentic example as it was split and found. The 1% touch-up can be seen on the part where the first right pleural tip was added. The only work done on the counterpart is a fracture repair through the cephalon. This trilobite is easily my favorite Cambrian fossil.

Acadoparadoxides sp. 16" (41cm)

Middle Cambrian - Asrir Tazlaft Mbr.

Jbel Wawrmast Formation, Morocco

A few finds from the Spense Shale here in SE Idaho.

A hyolith and a couple of little trilobite.

A very small trilobite.

And the most complete trilobite of the trip with a nice brach for a bonus!

Olenellus clarki

Providence Mountains, California

Context is critical.

That's a sweet ptrilo pic. i love Latham fauna. The providence has produced most of the finer Latham shale fossils I've seen. Well over and above the marble mtns. Did you collect the providence? Got any more?

I bought it in a rock shop 20 years ago. There is a counterpart as well. I would love to collect there, but I'm afraid the area is now within the Mojave National Preserve.

Context is critical.

YES! Your absolutely right! I was lucky enough to collect there just before they made it a trilobite preserve! Yes, a trilobite preserve. Making material from there, quite rare.

So what is a 'trilobite preserve'? It sounds like another term for 'trilobite destruction-by-weathering zone'. :)

Your right!! no collecting cambrian fossils, strictly, without a permit. Preserved for future research. I would love to go back

This is my favorite lower cambrian fossil. I collected it from the Latham shale in San Bernardino county, calif

Hi PRK,

Yes an olenellid but the genus / species is Bristolia mohavensis.

Congrats on another beautiful bug! 2722.gif

Ahh haa!! So it's been changed once again relativly recently. Cool! Cause there are lots of trilos with the Olenellus name. However I would much rather have a Bristolia. Much more diagnostic of the locality.

It was reassigned to Bristolia by Lieberman in 1999.

Attached is the info if you want to print it for your files.

I never thought about it, but I guess I was relativly lucky to live near a nice cambrian locality(a couple hundred km)

I love this little cambrian guy

Well said!

This is a fun topic.. All of my Cambrian fossils are my fav's (which is not very many - have not been able to buy very many and found even fewer myself).. hard to choose... but right now I think this one is my favorite, assuming the coloration is natural and not artificially applied (still researching):

apparently Pailiella pateliformis (medusoids), U Camb (Dresbachian) Mt Simon Complex, Mosinee WI

I have several but this slab may be my favorite one:

Zacanthoides liddelli Robison and Babcock 2011
(Note that this now may just be a variety of typicalis according to Andrew R C Milner, George Ast and Richie Kwik Kurkewicz )
Chisholm Shale, Middle Cambrian
Pioche, Nevada
Probably one of my top two or three special bugs, and it is a work of natural art with those colors as well. So my favorite piece hands down.

I have posted these before but they are my favourite Cambrian fossils in my collection. All found in Skåne, Sweden.

I like your Fallotaspis cf. bondoni Inyo. Those early Cambrian bugs. I have a nice Eofallotaspis from that same area, I guess just below your find. In the story of Cambrian trilobites the Fallotaspids are perhaps the most interesting, rare and show us the early trilobite form with thin shells that first appeared in the lower Cambrian. Special bug indeed. I am like you I could have put up lot of special bugs :)
